The post lie-preferably constructed of two vertical sections their ends to vertical bars 5 and 6, whereby they may moveparallelograimnatically, said bars beingpivoted at 7 to the post 2 adj acent a :the bar 6 andthe latter being provided with 1 silly inventionhas for itsobject lIOlfJIOVldB having ail-tendency to open the bars a being mounted in the channel thereof,

A suitable bottom 10 and a removable top 11 are provid-edi or the housing in order that the latter may be filled with rock, scraps of iron, or any other suitable material. a

In Fig. 1a fluid-pressure cylinder 12, pis- -to1113, and control valve are shown for ioperatmg the gate mechamcally, the piston 'belng connected with the lower end of bar 6 byta piston rod 15 and link 16 and the cylinp Y: derbein-g embedded in the earth; Pipes 17 1*: g. 3 is a-vertical section of the control extend to the opposite ends of the cylinder 12- trom the casing 18 of the valve let, the

valve proper 19 beingin the form of atapering1plug having avertical passage 20 inits periphery adapted to carry fluid pressure from the upper endof the housing 18 into -ei'ther pipe 17-, according tothe position to 'ment of the handle for 'controllingthe valve which said plug is turned; Opening through thelowerend otplug 19jand also tormedin l the periphery thereof, aretwo exhaust ports 21 adapted toflestablish communication betweeneitherpipe lT-and the lowerend of the casing 18, this-end ofsaid casing being 'providedwith an exhaust pipe 22 while the upper end thereof is equipped with a pressure inlet 23. It isintendedthat water pressure shall be used but it is obvious that compressed air,steam or thelike could well be employed. Regardless of the pressure used 7 movement of the plug 19 to one position will cause the piston 1.3 to be forced downwardly to open the gate, whereas turning of said plug to an opposed position will cause reversal of the piston to close said gate, Also
